HEAD-HOOP DIE.

Specification of Letters Patent.

Patented May 12, 1908.

Application filed May 5, 1906. Serial No. 315,347.

T 0 all whom it may concern:

Be it known that 1, WILLIAM H. POTTER, a citizen of the United States, residing at Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented a certain new and useful Improvement in Head- Hoop Dies, of which the following is a specification.

My invention relates to a new and useful improvement in dies for driving and setting the head hoop of barrels and kegs to be used in connection with hoop driving machines, and has for its object to so construct a die of this description that it may be readily attached to the driving arms of an ordinary hoop driving machine without interfering with the present method of driving the second. hoop into place but will also adapt the machine for driving home the head hoop.

With these ends in view, this invention consists in the details of construction and combination of elements hereinafter set forth and then specifically designated by the claims.

In order that those skilled in the art to which this invention appertains may understand how to make and use the same, I will describe its construction in detail, referring by letter to the accompanying drawing forming a part of this specification, in which Figure '1 is a side view of an ordinary shoe for driving the second hoop upon the barrel or keg showing my improved die in connection therewith for driving the head hoop. Fig. 2, a bottom view of Fig. 1. Fig. 3, a dctail view showing the arms of a driving machine with my improved dies attached thereto. Fig. 4, a section of my improved die clearly illustrating the groove around its edges for engaging the head hoop.

Referring to these drawings A represents my improved driving shoe having the corrugated surface B, and D is a lip formed upon this shoe which determines the distance to which the head hoop is driven upon the barrel by coming in contact with the chime of the barrel, thus acting as a gage so as to limit the downward movement of the arms and drive each hoop to the same distance from the chime of the barrel.

C represents the lower edge of the shoe and the surface B furnishes protection to the head hoop in the operation of driving.

E represents the ordinary die for driving the quarter hoop and bilge hoop which is placed against the bottom of the arms of the driving machine, and my improveddriving shoe is placed beneath this die, both being secured to the arm by suitable bolt. The die E is made in general shape a square having each of its sides curved inward, these curves being intended to coincide with the curvature of the hoop, and in the bottom face of the die along each of these edges is formed a groove F so as to produce a sharp edged lip for engagement with the top edge of the hoop to be driven.

In practice one of my improved driving shoes having been secured to the lower end of each of the driving arms G the head hoop is set upon the barrel and driven home by the shoe being moved downward by the arms, and when this hoop has been properly driven the arms are moved downward to the bilge hoopwhich is driven home by the die E and are thence moved upward to the quarter hoop which is driven home in the same mannor as the bilge hoop with die E. As the head hoop is driven home the surface B serves as a guide upon the sides of the barrel.

As before stated the dies E are curved inward so that it may be turned upon its axis, and either of these edges utilized for driving the hoops, or where various sized barrels or kegs are to be operated upon the curves in the sides of the die E may be of different radii so as to adapt it for use upon these various sized barrels and kegs.

By the use of my improvement at least half the labor in driving hoops upon a barrel is saved by the fact that the barrel does not have to be removed from the machine when the head hoop is placed, but remains in the same machine until the quarter hoop and bilge hoop are also placed, and this is of great advantage in the trade, producing better work and saving much time and labor. My improved shoe is also adapted for driving wooden hoops from the fact that the lip D is of sufficient width to engage the upper edge of the hoop without cutting into the same. It is to be noted that if desired the die E may be dispensed with and the shoe used independent thereof.
